WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 664,439, dated December25, 1900.

Application filed. June '7, 1900. Serial No. 19,423. (No model.)

My invention has relation to improvements in water-heaters; and itconsists in the novel arrangement and combination of parts more fullyset forth in the specification and pointed out in the claim.

In the drawings, Figure 1 is a middle vertical section taken through thecasing or drum on line 1 1 of Fig. 2, the burner being shown inelevation. Fig. 2 is a top plan view with the cover of the compartmentin which the oilreceptacle is placed removed; and Fig. 3 is a sideelevation of the device submerged in a bath-tub, the walls of the latterbeing broken away.

The present invention is an improvement on the water-heater for whichLetters Patent of the United States were issued to me under date of May8, 1900, numbered 649,111, and has for its object to materially simplifythe construction therein shown and described, with a view also tominimize the time within which a given quantity of water may be heated.In detail the invention may be described as follows:

1 Referring to the drawings, 1 represents a casing or drum havingadome-shaped top and provided at one end with an air-inlet flue 2 is cutaway at 9, the said recess or cut-away portion being of sufficient widthto allow for the accommodation of the cup 10, carried by the burner 11,the cup being intended, as is well known, to hold an initial quantity ofalcohol, which upon ignition heats the burner sufficiently to vaporizethe gasolene fed thereto in starting the flame. The flame shoots downinto the flue 2, the currents of air being induced thereinto, therebyproducing perfect combustion, the products of combustion filling thedrum and finally escaping through the flue 3. The top of the drum-ismade domeshaped in order that the products of combustion may properly bereverberated within the drum and the walls thereof heated in a minimumamount of time.

Like in my patented construction referred to the heater as a whole ispartially submerged in water, the heater being specially applicable forbath-tubs and the like.

It is apparent that I may make slightchanges in the construction withoutdeparting from the spirit of my invention.

Having described my invention, what I claim is A water-heater comprisinga suitable drum or casing having a dome-shaped top, an airinlet flue andan escape-flue, a compartment located at one end of the drum adjacent tothe air-inlet flue, a hydrocarbon-lamp located within the same, a pipeleading therefrom and passed through a recess in the adjacent wall ofthe casin g, a burner at the end of said pipe confined within theair-inlet flue, and adapted to direct its flame into the chamber of theeasing, the parts operating substantially as, and for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.
